Description
Volumetric flask, amber glass, LBG 3.3, Class A, with plastic stopper is a precision laboratory vessel for accurate preparation and measurement of light-sensitive solutions. Made from borosilicate glass LBG 3.3 in amber brown, it combines chemical resistance and thermal stability with effective light protection. The 25 ml nominal volume and 10/19 ground neck are calibrated to contain (TC, In) in line with ISO 1042 and DIN 12664, delivering Class A volumetric accuracy required in analytical chemistry, quality control and research. A polyethylene (PE) plastic stopper ensures a secure seal during mixing, standing and short-term storage of standards. Supplied by manufacturer Labbox in a practical pack of two pieces, the flask supports routine volumetric tasks such as preparing calibration solutions, performing dilutions and handling photosensitive reagents. Robust construction and standardised design promote consistent batch-to-batch performance, and a batch certificate is available as a free download for documentation. Clear graduation marking aids precise filling to the meniscus under controlled laboratory conditions.

Questions about Volumetric flask, amber glass LBG 3.3, class A with plastic stopper, 25 ml, 10/1
What is this article?
Volumetric flask, amber glass LBG 3.3, class A with plastic stopper, 25 ml, 10/1 is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Labware.
A volumetric flask is calibrated to contain one volume at a reference temperature, with a single mark on a narrow neck. Class A is the tight tolerance. It is not a storage bottle and it is not for heating. The stopper is part of the calibrated article.
Volumetric glassware is glass that has been calibrated to contain or to deliver one stated volume at a reference temperature. That calibration is the whole point. Class A and class AS have a tighter tolerance than class B. A volumetric flask contains. A pipette and a burette deliver. A measuring cylinder is the coarser reading, used when the volume is not the result. The classes sit under ISO laboratory glassware. The chain back to the unit of volume is the work of the BIPM and of NIST.
